摘要：NOVELTY - This invention involves a continuous and high yield separation method for 1, 3-propanediol from fermentation liquor by reaction-extraction coupling. The method comprises flocculation, monohydric alcohol recovery, reaction-extraction, hydrolysis, and distillation. The 1,3-propanediol obtained has purity above 99.5 wt.%. In addition, the invention overcomes the defects of existing technologies likesticking to wall and coking.
